My sis in law who got bored just by staying at home cleaning , cooking, taking care of the house, kids and all has decided to work again. Her 2 kids are also grown up (11 and 6) and don't need that much care like infants or toddlers. She was working before when she got married and before she got pregnant that's why I don't see her not wanting to work again.
Fortunately she landed a small job at a nearby cooperative and only works there 2x a week so she has still a lot of time with her family. On the side she also learn to sell some few things, like Avon (makeups), clothing etc. With those sales jobs that she has she was also able to generate a little income for her family.
